Viper 200.4 Class A/B 4 CH. Stereo Amplifier

Two 4 channel models cover the bases for essential multi-channel design, with built-in crossovers and bass EQ circuits on both the 200.4 and its big brother, the massive dual power supply 500.4.

• High-speed MOSFET switching power supplies and complimentary bipolar outputs (sub channel of model 1100.5 uses MOSFET outputs)

• All models over 300 watts feature dual power supplies for rock-solid power delivery under extreme conditions (400.2, 500.4, 1100.5, 550.6)

• Thermal, DC offset, reverse polarity and short circuit protection (1100.5 also features over/under voltage protection with status LED)

• Top-mounted controls easily accessed for system tuning (exc. model 150.2)

• All models feature built-in high performance, variable 12 dB/octave 2-way active crossovers (model 1100.5 sub channel features 24 dB/octave low-pass crossover)

• Variable 0-12 dB bass EQ function (models 150.2, 200.4, 500.4 have 8 dB Switchable bass EQ)

• Remote subwoofer level control (model 1100.5, option on model 550.6)

• 5- and 6-channel models feature 6 channel input for full access to source or processor output functions

• Expandable architecture features include buffered stereo full-range RCA output jacks (all models) and external bridging with an added model d600.1 class D mono amp (1100.5 only)

• Variable built-in 2-way crossover for RCA outputs supports any system design (model 550.6 only)

• Gold-plated power and speaker terminals and plugs and RCA connectors ensure maximum signal transfer

• Rugged one-piece extruded heat sink finished with injection-molded mounting feet
